Djokovic must have thought that this night is going to be a very relaxed night for him after taking a quick 2-0 lead in sets with little to no resistance from Wawrinka, but then Wawrinka was the old Wawrinka again and gave Djokovic a hard time to take home the 3rd set as well. For a second I was hoping that this could turn into a closer game much more than anyone could anticipate. I even put €0.60 on Wawrinka when he had the lead in the tie break now 
The odds were roughly 50 so why not... But it had to end as it had to end. Deserved win by Djokovic.
Djokovic in the tie break was quite superior, he had the highest percentage of 65.5% among the other players. Apart from Wawrinka who is quite old he is also not that great on grass so there are not many opportunities for him to beat Djokovic on the surface who is also one of Djokovic's favorites The odds were roughly 50 so why not... But it had to end as it had to end. Deserved win by Djokovic. https://www.atptour.com/en/stats/win-loss-index/career/tiebreak/all/
Zverev vs Berrettini, both players have the same weapon, namely serve and after taking a break in several tournaments due to injury Berrettini will again try to repeat his best performance two years ago by becoming a finalist, this match is very likely to be a match that lasts 5 sets.
